The sample to be detected can be a magnetic bead compound, and the magnetic bead compound comprises magnetic beads, antigens, antibodies and fluorescent biotin combined on the antibodies; the antigen is from a sample. Different magnetic beads can be combined with different types of antigens in a sample to form different magnetic bead compounds, joint inspection operation (namely immune joint inspection of a plurality of items) of detecting various parameter indexes can be realized by inputting the sample into the same reaction cup once, the detection process is simple to operate, and the detection efficiency is high.
The correction method of the embodiment comprises the following steps:

Alternatively, different magnetic bead complexes may be formed by adding different magnetic beads or fluorescent biotin-labeled antibodies of different intensities, or the like.
The control module 12 obtains detection data from the detection module 11, which may include at least three dimensions of detection data. The at least three dimensions of the detection data may be three dimensions of detection data, the detection data including in particular forward scattered light (FSC) detection data, side scattered light (SSC) detection data, and Classified Fluorescence (CFL) detection data, wherein the Classified Fluorescence (CFL) detection data is used to distinguish between different items, the forward scattered light (FSC) detection data and the side scattered light (SSC) detection data being related to the size of the microspheres. In other embodiments, the at least three dimensions of detection data may be other dimensions of detection data, such as four dimensions of detection data or five dimensions of detection data.

The control module 12 establishes a coordinate system with the forward scattered light as an abscissa and the classified fluorescence as an ordinate, and performs a bolus processing on the detection data to obtain a plurality of particle boluses as shown in fig. 4. The control module 12 obtains a first median of each particle group on the forward scattered light and a second median of each particle group on the classified fluorescence, for example, the first median is the median (or median) of each particle group on the forward scattered light, and the second median is the median (or median) of each particle group on the classified fluorescence.
The preset item range of the control module 12 includes a forward scattered light range and a classified fluorescence range corresponding to the particle cluster. That is, each particle group is provided with a forward scattered light range and a classified fluorescence range.
S302: control module 12 determines whether the first median is within the corresponding forward scatter range and the second median is within the corresponding classified fluorescence range.
The control module 12 compares the first median value with the corresponding forward scattered light range and the second median value with the corresponding classified fluorescence range, i.e. the first median value of the same particle mass is compared with the forward scattered light range of the particle mass.
If yes, the control module 12 determines that the first median is located in the corresponding forward scattering light range, and the second median is located in the corresponding classified fluorescence range, which is equivalent to that the item corresponds to a particle cluster, and the control module 12 does not need to correct the particle cluster.
If not, the control module 12 determines that the first median value is not located in the corresponding forward scattered light range, or/and the second median value is not located in the corresponding classified fluorescence range, then step S303 is performed.
S303: the control module 12 acquires particles within the range of the item as valid particles of the corresponding item to correct the particle cluster.
Optionally, the control module 12 corrects a plurality of particle clusters to obtain a plurality of corrected particle clusters, as shown in fig. 6, the items of the immunoassay analyzer correspond to one particle cluster, so as to improve the accuracy.
S304: the control module 12 saves the project range to the range array of the corresponding cluster.
The control module 12 obtains the range array in the process of performing the cluster grasping processing on the detection data, so that the control module 12 stores the project range to the corresponding range array of the particle cluster to correct the range array and improve the accuracy of the immunoassay analyzer.
In this embodiment, the control module 12 determines whether the first median is located in the corresponding forward scattering light range, and whether the second median is located in the corresponding classified fluorescence range; if not, the control module 12 obtains the particles within the item range as valid particles of the corresponding item to correct the particle cluster; the particle clusters can be corrected, the situation that the project in the prior art corresponds to two particle clusters is avoided, accuracy is improved, and implementation is easy.

In other embodiments of the present application, a person in the art may directly filter the detection data without setting the scatter diagram.
S702: the control module performs gaussian filtering, median filtering or mean filtering on the 12 scatter plot.
The control module 12 performs gaussian filtering, median filtering or mean filtering on the scatter diagram, for example, the control module 12 of this embodiment performs mean filtering on the first scatter diagram, the second scatter diagram and the third scatter diagram respectively.
S703: the control module 12 binarizes the filtered scatter diagram, performs an opening operation, and acquires a connected region to obtain a plurality of first clusters.
The control module 12 binarizes the filtered scatter diagram, performs an opening operation, and then obtains a connected region to obtain a plurality of first clusters. Wherein each connected region is the first particle cluster.
The control module 12 may obtain the connected region through depth-first traversal or breadth-first traversal, for example, the control module 12 obtains the connected region through depth-first traversal.
Optionally, in order to further remove the smaller connected region, the control module 12 is configured with a preset particle cluster area and a preset particle number, and calculates a first area and a first particle number of the first particle cluster; that is, the control module 12 calculates a first area and a first particle number of each first particle cluster, compares the first area of each first particle cluster with a preset particle cluster area, and compares the first particle number of each first particle cluster with a preset particle number. If the control module 12 determines that the first area is smaller than the preset particle cluster area or the first particle number is smaller than the preset particle number, the control module 12 deletes the corresponding first particle cluster, that is, removes the smaller connected region. If the control module 12 determines that the first area is larger than the preset particle cluster area and the first particle number is larger than the preset particle number, the control module 12 retains the corresponding first particle cluster to obtain the particle cluster corresponding to the item.
The control module 12 of this embodiment performs gaussian filtering, median filtering, or mean filtering on the scatter diagram; the control module 12 binarizes the filtered scatter diagram, performs opening operation, and acquires a connected region to obtain a plurality of first particle clusters, so that noise can be filtered, and the accuracy of the immunoassay analyzer is ensured.

S803: the control module 12 compares the number of all clusters with the number of items.
S804: if the control module 12 determines that the number of clusters is smaller than the number of items, the control module 12 corrects the clusters based on the median and the corresponding preset item range of each cluster.
Steps S801 to S804 are the same as steps S101 to S104 of the first embodiment, and are not described again here.
In step S803, the control module 12 compares the number of all clusters with the number of items. If the control module 12 determines that the number of clusters is smaller than the number of items, the process proceeds to step S804. If the control module 12 determines that the number of clusters is equal to the number of items, it proceeds to step S805.
